如何启用捏和伸展我的应用程序的用户界面 [英] How can i enable pinching and stretching on my app's UI

问题描述

我已经在这一个TextView表布局。由于每一个行内的文本是足够小，以适应屏幕上，我希望我的用户能够捏和伸展屏幕，使他们可以放大。但是，目前该功能默认情况下不工作。我怎样才能使捏和拉伸画面，然后呢？

I've a table layout with a textview in it. As the texts within every row are small enough to fit into the screen, I want my users to be able to pinch and stretch the screen so that they can zoom in. But, currently that feature is not working by default. How can i enable pinching and stretching the screen, then?

感谢

推荐答案

您可以自己实现它。 ：通过阅读本教程多部分启动http://www.zdnet.com/blog/burnette/how-to-use-multi-touch-in-android-2/1747 （第6部分是专门捏和变焦），这等岗位中在开发者博客：的http://android-developers.blogspot.com/2010/06/making-sense-of-multitouch.html

You can implement it yourself. Start by reading this multipart tutorial: http://www.zdnet.com/blog/burnette/how-to-use-multi-touch-in-android-2/1747 (part 6 is devoted to pinch and zoom) and this other post in the devs blog: http://android-developers.blogspot.com/2010/06/making-sense-of-multitouch.html

还有那看起来很有希望（虽然我没有尝试）库： HTTP：//$c$c.google.com/p/android-pinch/

There's also a library that looks promising (although I did not try it): http://code.google.com/p/android-pinch/
